DTC P1605: Rough Idling [02/2014 - 11/2016]: Description
WARNING: This page is about a different variant/trim than selected.
When the engine is idling stably under a low load, if the idle speed drops or becomes unstable, this DTC will be stored.
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can be helpful in determining whether the vehicle was running or stopped, whether the engine was warmed up or not, whether the air fuel ratio was lean or rich, as well as other data recorded at the time of a malfunction.
